NP, let's stick to a generic example then, redacted down to the bare minimum
backend st-min
# log request rate over 1 minute
stick-table type ipv6 size 1g expire 2m store http_req_rate(1m)
backend st-min-url
# log request rate per distinct url+ip(v4/6)
stick-table type binary len 8 size 1g expire 2m store http_req_rate(1m)
backend dc
# works perfectly as expected
http-request track-sc0 hdr_ip(x-forwarded-for) table st-min
# need url32+hdr_ip(x-forwarded-for) here, as src is another haproxy
http-request track-sc1 url32+src table st-min-url
# augment on to request headers
http-request set-header X-HA-Min-Rate %[sc_http_req_rate(0)]
# send tracked sc-hour variables to core
http-request set-header X-HA-Min-Rate-URL %[sc_http_req_rate(1)]
# whatever backend
server localhost localhost:81 check
Hope this clarifies, haproxy -vv output follows, however any version will do
haproxy -vv
